System Power ICs for CCD Camera in Mobile Phones
03.16.2005
ROHM's BD6023AGU and BD6025GU series system power supply ICs for integrated CCD sensor in mobile phones and a display LED driver into a single chip. A chopper-scheme voltage booster circuit in the power source allows it to respond to an increased load current caused by increasing pixels. Both series balance high performance and low power consumption and are offered in a compact VCSP85H5 (5.5mm × 5.5mm) package. In comparison with existing technology, the VCSP85H5 package is 36% smaller. Using this IC results in a reduction in the number of internal components in the mobile phone by 52%.
